This document outlines the policy for managing gallstones disease and emergency admissions related to biliary colic or acute cholecystitis. It describes the appropriate diagnostic investigations and treatment approaches based on ultrasound findings and liver function test results. For biliary colic with normal ultrasound and tests, elective laparoscopic cholecystectomy is discussed. For abnormal ultrasound or tests, further imaging and potential endoscopic retrograde cholangiopancreatography is recommended before considering early cholecystectomy. For acute cholecystitis, the priority is emergency laparoscopic cholecystectomy within 3-4 days if the patient is fit, with conservative treatment or percutaneous cholecystostomy as alternatives if not.
